  * Interface for listening to <code>null</code> selection changes.
  * <p>
  * This interface should be implemented by selection listeners
  * that want to be notified when the selection becomes <code>null</code>.
  * It has no methods. It simply indicates the desire to receive
  * <code>null</code> selection events through the existing
  * <code>selectionChanged</code> method. Either the part or the
  * selection may be <code>null</code>.
